Product Description

Product Description

M42 1.3247 SKH59 High Speed Steel Round Bar and Plate

1. M42 steel introduction
M42 Tool Steel is is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. (HSSSteel M42) 8% Cobalt tool bits are designed for machining work hardening alloys and other tough materials. They have increased water resistance and tool life. This improves performance and retention of the cutting edge. M42 steel composition makes for a good combination of toughness and hardness.
